Based in this article from GeekWire, it looks like the University of Washington (a public institution, I believe) may have set itself up for a bit of a First Amendment issue with its “Live Coverage Policy” for journalists credentialed to cover its sports program.

The policy explicitly limits journalists to 20 Tweets per basketball game and 45 per football game. Violations can result in revocation of the violator’s press credentials. As a public institution, and thus, arguably, a “state actor”, the UoW may be violating the First Amendment with this policy.
Even if it is not, it certainly raises (once again) the issue of social media in the press and what its implications are for First Amendment speech (including, but not limited to freedom of the Press).

Of course, there are (albeit distant and indirect) additional issues of trademark, fair use, and the role of public university ownership and use of intellectual property implicated in these situations as well. Those, however, are subjects for another time.
